Good news and bad news. The good news: You can burn 324 calories a day commuting! The bad news: YOU probably won't.

A new study found that commuters who take a subway, train, or bus can burn 162 calories going back and forth to work . . . between about 10 minutes of standing, two flights of stairs, and another 11 minutes of walking each way.

They didn't figure out how many calories you burn when you sit while you commute and drive yourself door-to-door . . . but we're thinking it's a lot closer to zero. (FemaleFirst)
